ABS 3D printer ALTRA 670

PLAglass fiber reinforced plasticpolyamide

Product Overview
The BigRep ALTRA 670 is a large-format, high-temperature industrial 3D printer designed for continuous production of complex, production-grade parts up to 1200 mm in length. It provides a thermally stable heated build chamber, automated calibration and monitoring, integrated material storage and remote visibility for reliable, repeatable manufacturing.

Key Features

• Large heated build chamber: 670 L chamber heated up to 140°C for thermal stability on large parts.
• Massive build volume: supports parts up to 1200 mm in length; full build envelope 700 × 1200 × 800 mm.
• Dual DSX extruders: Direct Synchronized Extruders with integrated cooling and sensors; Relay Mode enables automatic switchover when a filament spool is depleted.
• High-temperature capability: nozzle temperatures up to 450°C to process engineering and high-performance polymers.
• SWITCHPLATE heated print bed: flexible magnetic plate with embedded wiring for homogeneous temperature and strong first-layer adhesion; removable for part extraction.
• Keep-dry material storage: sealed chamber for two spools to protect hygroscopic polymers.
• Automated quick start and calibration: topology measurement, adaptive mesh bed leveling and automated calibration reduce setup time and errors.
• Integrated sensors and remote monitoring: onboard sensors plus HD wide-angle camera for process visibility.
• Air cleaning unit: HEPA and activated carbon filters for improved workshop air quality.
• Open Material System: compatible with BigRep and third-party filaments, including many engineering and high-temp materials.

Applications

• Aerospace-grade parts: production-capable components designed to withstand heat, vibration and mechanical stress.
• Functional prototypes and product development: evaluate designs at operating temperatures with production-grade polymers.
• Durable tooling, jigs and fixtures: in-house manufacture of wear- and deformation-resistant tooling for production use.
